How many kilometers should the belt of Baojun 730 be replaced?
2 Answers
Baojun 730 belt replacement time is three years or 50,000 kilometers. The following is the relevant introduction to Baojun 730 belt replacement: 1. The replacement time for new cars can be appropriately extended. The fact that the timing belt is not broken does not mean there are no problems. As the belt ages, the degree of stretching will inevitably exceed the compensation range of the tensioning device, causing the timing sprocket to slip. Additionally, tooth wear and the presence of lubricating oil can also lead to slipping. 2. If the belt shows signs of reduced hardness, erosion, fiber breakage, cracks, or fissures, it indicates that the belt is damaged and should not be used further. The high temperature during engine operation, cooling after the car is stopped, oily impurities, and improper matching or installation of the timing belt tensioner can all shorten the service life of the timing belt. 3. The timing belt is responsible for the accurate coordination of key parts of the engine, so it is crucial for the normal operation of the engine. Once the timing belt is damaged, the valves and ignition will stop or malfunction, causing the engine to stop working. In severe cases, the cylinder head may also be damaged. 4. The timing belt is a consumable part. Once it breaks, the camshaft will not operate according to the timing, which is highly likely to cause severe damage due to the collision between the valves and pistons. Therefore, the timing belt must be replaced according to the mileage or time specified by the manufacturer.
As a veteran driver who has been driving the Baojun 730 for many years, I believe the timing of belt replacement is crucial. Generally speaking, the timing belt needs to be replaced approximately every 60,000 to 80,000 kilometers—don’t wait until it breaks to regret it. Last time I checked my car at 70,000 kilometers, the belt already had fine cracks, and fortunately, I replaced it in time, avoiding major engine damage. I recommend giving the belt a quick visual inspection every 5,000 kilometers to check for wear or cracks on the surface. Also, pay attention to any unusual squeaking sounds, as this is often a warning sign. Additionally, high temperatures or dusty environments can accelerate belt aging, so in mountainous or coastal areas, it’s advisable to shorten the replacement interval. Remember, a small oversight could lead to thousands in repair costs—safety first!
